Harryc yes you are right I was in the middle of somthing at work and was not going to post but must have ( brain fart) . The only differance you may see if you use 18ms or 21ms is when you use servo reverse the servo center may move. This is the same thing as when you use different mfg's servos on your factory systems
No it won't proline. The centre is determined by what the servo has been designed to use as centre timing in the data pulse. If a servo was designed to centre at 1.5ms and you send it a 1.5ms pulse, the servo will centre. It makes no differnce if you send it the 1.5ms pulse once every 18ms or once every 21ms.
